MNBB with coumadin for A-fib

would you stop coumadin for 5 days on an elderly patient with A-fib for MNBB? According to 2015 ASRA guideline MNBB is considered intermediate risk procedure in general and high risk in someone on anticoags. coumadin needs to be stopped for 5 days with normalization of PT/INR. On the other hand, I'm not sure if it outweighs the risk of thromboembolism for someone with A-fib.
